Trying to get nodata in GeoTIFF to display as transparent
This post was updated on .
Per the topic, I'm trying to get nodata areas that currently display as black in GeoServer/WMS to display as transparent. The GeoTIFFs in question have three bands - red, green, and blue - each with a NoData value of 0.0.
I suspect I need to use SLD to do this, but I can't find any information on using SLD to just make nodata areas transparent and leave the color bands alone.
// Edit: Also, adding transparent=true to the WMS request does nothing.
